World’s Largest 7-Layer Die – Just One of Our Leading Edge Technologies

 

Davis-Standard supplies blown film extruders, extrusion lines and associated winders, dies and feedscrews for blown film processors around the globe. Our mono and multi-layer blown film technology is used for applications ranging from agriculture and greenhouse films, to packaging and shrink films, to stretch and collation films. 

 

Our blown film offering is defined by maximum value with a global approach. We deliver more throughout the blown film process with high-performance extruders and equipment for processing EVA, LDPE and LLDPE films, as well as proven extrusion technology for SOE (slit-on-edge), BUR (blow-up ratio) and DDR (draw-down ratio) technology. We are proud to offer the industry’s largest seven layer blown film die, efficient WesJet air rings, precision gauge control, and world renown DSB® feedscrew designs.

Davis-Standard is a global extrusion leader in flexible packaging with lamination lines capable of 2000 feet per minute. We understand the needs for high-speed converting machinery, especially in the area of laminating films where roll geometry and layer uniformity leads to faster speeds on converting and laminating lines. Uniform layers enable cost efficient use of  expensive materials, and our lines have been effective in producing economical coex structures. Advantages such as stationary die systems, oscillating haul-offs, and roller-collapsing frames produce flat, smooth film and rolls. Our systems are also know for consistent symmetric and asymmetric films.

Davis-Standard, LLC is the industry leader in developing innovative technology for large and wide blown film systems for industrial film and bag applications. There is no better blown film extruder for high output and low melt temperature than the MAC extruder with the DSB®II feedscrew. This extruder, specifically for blown film, leads to the best and most consistent melt quality (temperature uniformity to 2 degrees F and pressure variation <1%), which is necessary to achieve uniformity from large dies. Blown film die systems can oscillate up to 1.2 meters in diameter or remain stationary up to 2.1 meters in diameter. These systems produce controlled property films at wide widths with flat rolls.

Davis-Standard's blown film flexible packaging solutions for high-speed converting machinery lines are unsurpassed. This is especially true in the area of barrier films where roll geometry, thickness and layer uniformity lead to faster conversion speeds on pouch lines, FFS machines and laminating lines. Uniform layers enable cost efficient use of expensive materials, and our blown film lines have proven effective in producing economical coextruded structures. Advantages such as stationary die systems, oscillating haul-offs, and roller-collapsing frames produce flat, smooth film and rolls. Our blown film systems are also known for consistent symmetric and asymmetric films.

Davis-Standard understands the primary goal in can liner systems is output. Rates over 25 ppi and increased uptime are trademarks of our industry-leading blown film systems. Our die systems are stationary with oscillating haul-offs so that jumbo rolls can be made for off-line converting. Other advantages include:

  • Super air-cooled MAC extruders with a high-volume suction blower concept for superior cooling and low maintenance
  • Pre-wired control panels mounted on extruder base to reduce installation time
  • DSB®II feedscrews with high output mixing

Davis-Standard, understands stretch wrap systems. Whether cast or blown film, our technology is applied to all components. Roll geometry and unique small roll winders efficiently allow for high production rates by providing reliable, consistent automated roll handling. Die systems are stationary up to 1-meter in diameter. Oscillating haul-offs and roller collapsing frames produce flat, smooth film and rolls. Oscillating die and stationary haul-offs are also available. These systems produce symmetric and asymmetric films.

Specific to agricultural stretch films, our technology is focused on uniform quality and thickness. This provides excellent stretch properties with consistent cling levels, strong puncture resistance, high load retention for bale integrity, low oxygen and water permeability.
